CHARLES J. SEYMOUR, OF BROOKLINE, MASSACHUSETTS.

ELEVATOR AND CONVEYER'.

SPECIFIGATIdN forming part of Letters Patent No. 404,660, dated June 4,1889.

Application filed August 20, 1888. Serial No. 283,209. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES J SEYMOUP, of Brookline, in the county ofNorfolk and State of Massachusetts, have invented certain new and usefulImprovements in Elevators and Conveyers,of which the following is aspecification.

My invention relates to elevators and conveyers generally, though, ashereinafter described and explained, it has'particular relation to meansfor unloading coal and the like from boats or vessels.

My invention will first be described in connection with the accompanyingdrawings, forming a part of this specification, and then pointed out inthe claims.

Of said drawings, Figure 1 is a vertical longitudinal section of avessel, showing the construction and v arrangement of my improvedconveyer and elevator in connection therewith and the manner of usingthe same. Fig. 2 is a crosssection on the line a: as of Fig. 1. Fig. 3is a diagram illustrating the construction and operation of my improvedmeans for opening and closing the bucket or pan supplying holes in thefloor of the vessels hold.

The same letters and figures of reference designate the same parts andfeatures wherever they occur.

In the drawings, a designates the frame of the vessel constructed with atrough or way running longitudinally over the keel beneath the floor ofthe hold.

I) designates an endless chain of buckets or pans arranged to run overthe draft-wheels 2 and 3 and around the idle wheels or pulleys 4 and 5and over the head 0 on the elevatorframe (Z. Tracing the chain ofbuckets and pans a from the pulley or wheel 5, they pass up 011 one sideof the elevator-frame cl, around draft pulley or wheel 2, over head 0,down on the opposite side of the frame cl, around draft-wheel 3, throughthe lower part of the chamber, over the keel and beneath the floor,around wheel 4, and back just beneath the floor to and around idle-whee15 to the point of starting. The several wheels 2, 3, 4, and 5 areconstructed as sprocket-wheels to engage the shafts or other parts ordevices of the chain of buckets and pans and carry the same around,thewheels2 and 3 being positively driven, and hence herein calleddraftwheels, and the wheels 4 5 being idle or guide wheels and operatedmerely by the movement of the chain of buckets and pans.

The head 0 of the elevator-frame overhangs or projects out from the lineof travel of the chain of buckets and pans, so that the coal or othermaterial taken by or delivered to said buckets and pans may, as thelatter pass around the overhanging portion of the head, be dumped intothe chute 6, while the buckets and pans pass around under theoverhangingportion of the head and down again close to the line ofascent, as shown in Fig.1. This construction enables me to economizeroom to the greatest possible extent in the operation of the chain ofpans and buckets.

Itwill be understood, of course, that suitable tracks 25 are provided toguide and support the chain in its movements, the tracks around theoverhanging portion of the head down the front of the elevator-frame andunder the inwardly-traveling portion of the chain being doublethat is,one over-and one under the wheels on each side.

fdesignates holes or delivering-ports formed in the bottom of the vesselon a line over the line of horizontal travel of the buckets and pans,through which ports the coal or other material is delivered to saidbuckets and pans. Preferably but one of these ports f (thatnearest theelevator-frame d and capable of delivering coal) will be open'at a time.

With a substantially fiat floor in the hold or apartment where the coalor other article is stored (which construction is necessary to a maximumamount of storage-room) after all of the coal has been delivered to thebuckets that gravity will carry down thereinto there will still remain avery considerable amount at the sides of the holes or ports f, and inorder to cause this undelivered portion to run or slide into the bucketsthrough the ports I form the floor in movable sections g, hinging theedges of said sections along the line next to the ports f to the frameof the boat or vessel, and leaving the outer portion of each section gso that it can be raised or swung upward, and thus cause the coal orother material thereon to run down into the adjacent port f.

' tioned figure.

In order that no coal on the hinged section g may fall down back of orbehind the same as it is raised, and consequently swung inward from theside of the boat or vessel, I hinge a leaf or shelf 71 to the side ofthe boat above the free edge of the movable section g, with the freeedge of the said leaf h resting on the upper surface of said section g,so that as the latter is raised the free edge of the leaf or shelf maybe moved outward in eontact therewith, and so prevent the coal fromfalling behind or under the floor, all of which will be clearlyunderstood by an inspection of Fig. 2, where the full lines representthe position of the parts before the floor is raised, and thedottedlines show such position afterward.

To keep the coal from running down under the floor at the ends of thesections 1, when the latter are raised, I construct partitions 1'between each two adjacent sections, which partitions may extend up to aline a little? higher than the plane to which the sections 9 are raised,as will also be understood by reference to Fig. 2, the ends of thesections g in the raising and lowering of said sections moving in closeproximity to said partitions.

The sections g and leaves or shelves 71. may be operated by means ofchains or cables j, attached thereto and passing over pulleys 7.1, or beotherwise suitably arranged.

To provide suitable covers or cut-offs to the ports or holes f, wherebythe latter may be opened and closed, as may be desired, I pivot or hingedoors 7t at one of their ends, as at Z, to the frame of the vessel, sothat said doors may be swung around under the floor and under ports f,and so close or cut off said ports, as shown by dotted lines in Fig. 3,or be swung outward, and so open said ports, as represented by fulllines in the last-melt The doors k will at their free ends be guided andsupported in their movements by suitable tracks or ways m, and may beoperated by means of chains or cables 97. a, secured thereto and passingaround pulleys. The swinging movement of the doors It may be limited bysuitably-positioned stops q, as shown.

I am aware that sliding doors or cut-offs or covers have been employedin similar connections and for similar purposes on docks, &c., and henceI do not claim the same, broadly.

Either wheel or pulley 2 or 3 may be the driving-wheel, operated fromany prime motor, and the other be driven from it by means of a chain orbelt, as will be understood by an inspection of Fig. 1.

It is obvious changes may be made in the form and arrangement of partscomprising my improvements without departing from the nature or spiritof the invention.

\Vhat I claim is- 1. The combination, with avessel provided with atrough or way beneath the floor and above the keel, of avertically-arranged elevator-frame at the end of such trough or way, anendless chain of buckets and pans arranged insaid trough or way and onsaid elevator-frame, and wheels to move and guide said chain, wherebythe coal or other contents of the vessel may be taken therefrom andcarried directly to and up the elevatorframe to be discharged, as setforth.

The combination, with a vessel provided with a trough or way beneath.the floor and above the keel, of a vertically-arrangod elevator-frame atone end of such trough'or way, said elevator-frame being provided withan overhanging head 0, an endless chain of buckets and pans arranged insaid trough or way and on said elevator-frame, and wheels or pulleys andtracks i to move and guide said chain of buckets and pans, as set forth.

3. The combination, with a vessel provided with delivering holes orports in its floor, of movable sections 9 of the floor, hinged at pointsat or near said delivering holes or ports, and leaves or shelves 71hinged to the side of the vessel, with their free edges in contact withsaid hinged sections of flooring, as set forth.

4c. The combination, with a vessel provided with delivering holes orports in its Iloor, of movable sections g of the floor, hinged at pointsat or near said delivering holes or ports, leaves or shelves 7:, hingedat the side of the vessel, with their free edges in contact with saidhinged sections of flooring, and partitions 21 between each twosections, as set forth.

5. The combination, with avessel provided with delivering holes or portsin its floor, of covers or cut-offs for said holes or ports, said coversor cut-offs being pivoted beneath the floor and provided with cables,whereby they may be swung around to close the ports or holes, or bemoved in the opposite direction to open the same, tracks in beneath thefree ends of the corners or cut-cits to support the same, and stops tolimit the movementof the covers or cut-offs, as set forth.

In testimony whereof I have sign ed my name to this specification, inthe presence of two subscribing witnesses, this 18th day of August, A.D. 1888.

CHARLES J: SEYMOUR.
